The LG THERMA V Split is a hydro box type comprising a
separate indoor and outdoor unit, which are connected
by refrigerant piping. Hydronic components such as plate
heat exchanger, expansion tank and water pump are
located within the indoor unit, making the unit capable of
withstanding freezing outside ambient temperatures.

ENERGY STATES INTERLOCKThe R32 Split & R410A Split provide provides energy state interlock function that enables customers to use as much as
possible of their own renewable energy. It can shift set points depending on input signal from Energy Storage System (ESS)
or any other third-party device using Modbus or Digital 230V inputs.
• SoC : State of Charge • Surplus Power (SP) = PV Power – Load Power• Area of Energy State for ESS can be adjusted by ESS.
* Contact signal designated ES3 and ES4 can be changed to ES5 ~ ES8.** Offset values of heating, cooling and DHW are changeable.*** Therma V can connect not only ESS but also 3rd party controller through Modbus, in that case, ES1 to ES8 are used.

In this mode, the target temperature will vary according to the outdoor temperature automatically. This mode adds the cooling
season function to the conventional weather dependent operation mode. Moreover, this function can be conveniently set
using visualized graphics.
SEASONAL AUTO MODE
ADVANCED PUMP CONTROL OPTIONSVarious pump control options are possible for the user’s convenience. With the the R32 Split & R410A Split, the water flow
rate can be changed as per heat load condition, therefore it makes more energy efficient operation during low load condition.
WATER CIRCUIT MONITORINGIt is possible to monitor via remote controller not only temperature of water circuit but also flow rate and pressure.
This information is not only useful to the installer during installation, but also helps to periodically clean the strainer.
Flow Rate 40 LPM (L/min)
Water Pressure 1.6 bar

MODBUS COMMUNICATIONConsidering the units in parallel installation, it is required to think how to control them. The R32 Split & R410A Split can be connected
to 3rd party control system using Modbus protocol directly, without Modbus RTU gateway and PI485 gateway. Moreover,
The R32 Split & R410A Split is able to support much more functions than conventional one using new Modbus memory map.

1. Due to our policy of innovation some specifications may be changed without notification.2. Wiring cable size must comply with the applicable local and national codes. And “Electric
characteristics” chapter should be considered for electrical work and design. Especially the power cable and circuit breaker should be selected in accordance with that.
3. Sound power level is measured on the rated condition in according with ISO 9614 standard. Therefore, these values can be increased owing to ambient conditions during operation.
4. Performances are based on the following conditions (It is according to EN14511) : • Interconnected pipe length is standard length and difference of elevation (outdoor ~ indoor
unit) is 0m.5. This product contains fluorinated greenhouse gases.
1) When fan coil unit not used. 2) DHW 58 ~ 80°C operating is available only when the booster heater is operating.
